Alongside her current track, Lewis treated fans to an exclusive preview of her highly anticipated new LP by performing 'Glassheart', which she previously confirmed was co-written by herself and Ryan Tedder.

Speaking to Digital Spy prior to the gig, Lewis explained that she had gone to Denver to spend time with the OneRepublic frontman and his family.

Admitting that she had been "down" at the time, she recalled: "I remember just not wanting to sing a ballad or anything that would make me more sad. I was like, 'Can you give me a song where I can just dance and jump around?'

"He was like, 'What about this?' - he played this beat and it was really hypnotic. So I was like, 'Yes! We have to do this'."

Lyrics include: "Baby if you love me let me know / 'Cause everything you hurt you've hurt before / You're about to tear this love apart and break another glassheart."

Previously teasing the material he worked on with Lewis, Tedder told Twitter followers that the new sound, which he said was "inspired by Tron and other things", would "surprise and maybe even shock" people.

"It's a little bit Tronny because he's used these synthetic melodies that go up and down the scale, really, really fast," Lewis said.

'Collide' is out now, while album Glassheart is released on November 28.
